STEAM-TRAP.

Specification of Letters Patent.

Patented July 3, 1906.

Application filed June 10,1905. Serial No. 264.589.

To all whom it may concern;-

Be it known that 1, WILLIAM H. GooGINs, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Steam-Traps, of which the following is a specification.

My invention relates to steam-traps and devices having like function by the operation of which condensation water directed into a closed elevated chamber is intermittently returned to the boiler by the pressure of steam and the weight of the water.

The object of my invention is the production of steam-trap mechanism of special and peculiar construction designed to insure certainty of operation and adapted for adjustment to return the water to the boiler at shorter or longer intervals of time, as may be desired. One use of my invention is that of a boiler-feeder, and it is desirable in certain cases to deliver to the boiler water in larger quantities and at less frequent intervals than under conditions where the condensation water only is to be returned. i

I accomplish the stated objects by constructing and associating the parts illustrated in the drawings herewith, of which Figure 1 represents a vertical crosssection of the invention lengthwise of the tilting pan. Fig. 2 is a cross-section of the whole vertically and transversely of the tilting pan. Fig. 3 is a front view of the water-gate plate or partition, and Fig. 4 represents a vertical cross-section of the steam-valve on a larger scale than that of the other views to more clearly show its construction.

Like letters of reference are used to designate like parts throughout.

The letter A marks the casing or chamber of the trap, which is provided with an airvalve B at the top and may have also a relief-valve G at the side to permit steam to escape when it is desired to start the trap promptlyfor example, after a new adjustment has been made, as explained below.

A pipe D connects with the boiler and includes the check-valve E, opening toward the boiler, as usual, and the pipe F conducts the condensation water into the trap and is provided with a check-valve G, preventing the return of water or steam from the trap in the ordinary manner.

The tilting pan is designated by letter H. It is divided into two compartments, the lefthand compartment J receiving the water first and the right-hand or overbalance compartment K being later served with water through the overflow-opening-L of thewatergate plate M. The overflow-opening is governed by the vertically-sliding gate-plate N, having the recesses O and being secured to the plate M by screws P. It will be understood that the opening may be rendered smaller or larger by the vertical adjustment of the gate-plate, and by forming the lower edge of plate N in a broad V shape the opening' may at the outset be made very small compared with the whole. The result of this construction is that the receiving-compartment is almost filled when the overflowopening is relatively small, and the overbalance-compartment is not sufficiently filled for some considerable time to cause the pan to tilt and empty. On the other hand, if the overflow-opening is fully open the overbalance-compartment fills at once at short intervals and the pan tilts. WVhen empty, the pan H has one corner resting upon the shelf Q, (shown in Fig. 1,) and it is held in this po sition by reason of the greater weight of the receiving-compartment empty and including the resetting-weight R. The axis of the pan is marked S, and by means of the cam T at one end, as shown in Fig. 4, the valves U are raised from their seats V as the pan tilts. The introduction of the cam enables the tilting pan to raise the valves, even through there is but little water in the pan. The lift of the valves is not great, while the leverage of the pan and its contents are considerable. The casing W of the valves U is connected with the steam are aof the boilers, and the pipe X, leading from it to the upper part of the trap, as shown in Fig. 2, admits live steam to the trap when the pan tilts and fills the trapchamber to boiler-pressuret emporarily and for a time suflicient to enable the water deposited by the tilting pan to run down the pipe D into the water area of the boiler. I

I am aware that steam-traps are constructed containing tilting pans, and I do not claim that feature.

What I claim is- 1. In a steamtrap, the combination with an exterior casing, of a tilting pan pivotally supported within said casing and having a receiving-compartment and an overbalancecompartment and a partition whereby one compartment may overflow into the other, a steam-valve adapted to admit steam into the casing, valve-operating devices constructed and arranged to be actuated by the tilting pan whereby said steam-valve is operated, and a discharge-pipe leading from the casing.

2. In a steam-trap, the combination with a tilting pan having a receiving-compartment and an overbalance-compartment, the said compartments being separated by a partition having an opening, of a steam-valve adapted to admit steam to the trap and arranged to be operated. by the tilting pan.

3. Ina steamtrap, the combination with a tilting pan having a receiving-compartment and an overbalance-compartment, the said compartments being separated by a partition having an opening, of an adjustable gateplate whereby the overflow-opening may be covered, and a steam-valve adapted to admit steam to the trap and arranged to be operated by the tilting pan.

4. In a steam-trap, the combination with a rocking axis, of a cam attached to the axis,

and a steam-valve adapted to admit steam to the trap and arranged to be operated by said cam.

5. In a steam-trap, the combination with a tilting pan, of an axis secured to the pan, a cam secured to the axis, and a steam-valve adapted to admit steam to the trap and arranged. to be operated by the tilting pan.

6. In a steam-trap, the combination with a tilting pan having a receiving and an over balance compartment and a partition whereby one compartment may overflow into the other, of an axis secured to the pan, a cam secured to the axis, and a steam-valve adapted to admit steam to the trap and arranged to be operated by the tilting pan.

In testimony whereof I aiiix my signature in presence of two witnesses.

WILLIAM H. GOOGINS.
